-Small enough for the fitted jeans pocket. I carry it around 24 hours a day so it shouldn't be too fragile.
-Time to first shot should be as fast as possible. Can't miss my friends guzzling their shots.
-Low light performance as I'm mostly inside when I shoot with friends.
-Don't care about price, I take lots of pictures so an extra $100 now seems like no big deal in the long run.
-Don't care about video, zoom

I've been looking at:
Canon s95
Canon sd4500
Sony DSC-WX5

Thoughts:
-s95 has best low light photos but is a little bigger than the Sony and from some stuff I've read, the performance may not be stellar.
-sd4500 - better auto modes? (I don't use manual controls)
-Sony can't find too many reviews yet but I love the size.

Any other ultimate jean cameras I should look at? Any thoughts out there?

S95 for the low light, the other are not at the same level with the smaller sensor.
but if you want fast to fire and short shutter lag, casio's are some of the fastest in that department with point and shoots.

I probably should just get the S95. It seems like you can't go wrong with it. I just didn't know if there was anything smaller or faster that takes close to the same clarity of low light pictures. From the reviews I've read it seems like 'the only game in town' for low light pocketable cameras.
